The southern grey-headed sparrow (Passer diffusus) is a passerine bird of the sparrow family Passeridae. It is sometimes treated as a subspecies of the grey-headed sparrow. It is found in savanna and woodland in Angola and Zambia southwards into South Africa, where it is expanding its range and is kept as a caged bird, like its relative the white-rumped seedeater.

Likely
About 50% of wildlife watchers report a Southern Gray-headed Sparrow sighting in Lower Zambezi National Park on a given day, based on 150 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 37th most-seen of the 241 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Southern Gray-headed Sparrow in Lower Zambezi National Park on a given day, against about 30% in May, the lowest month. That is one of Lower Zambezi National Park's driest months, with almost no rain against 290 mm in January. February and March have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Southern Gray-headed Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 25
Of the 25 parks where we can rate Southern Gray-headed Sparrow sightings, Lower Zambezi National Park ranks 5th at about 50%. The best odds are in Gonarezhou National Park (Zimbabwe, about 60%), Mana Pools National Park (Zimbabwe, about 50%) and uMkhuze Game Reserve (South Africa, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Southern Gray-headed Sparrow is recorded against all the birds logged in Lower Zambezi National Park (150 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
